Unit 8 Worksheet 1- continued

         Assume that the car in Figure 1 is going at a constant speed. We will define centripetal force to be the net inward force.

         Figure 1

1.      Construct a qualitative motion map of the car in Figure 1.

2.      Is the car in Figure 1 experiencing an acceleration? If your response is yes, in what direction? (Explain how you know.)

3.      Construct a qualitative force diagram for the car in Figure 1. (Justify the relative forces in your force diagram.)

4.      If the speed of the car in Figure 1 is 43 km/h, its mass is 1200 kg and the radius of curvature (r) is 25m, determine the magnitude of the centripetal force acting on the car.

5.      Construct a quantitative force diagram for the car in Figure 1.

6.      What is the acceleration of the car depicted in Figure 1? (If the acceleration is not equal to zero, then illustrate magnitude and direction with a vector diagram.)

7.      If the driver of the car in Figure 1 weighs 540 N, construct a quantitative force diagram to illustrate the forces acting on the driver.

8.      What is the magnitude of the upward force that the seat is exerting on the driver?
